After Doctor Who's last Cold War adventure, the Doctor and his companion are traveling back a decade.

On Saturday's episode, "Hide" (airing 8/7c on BBC America), the time-hopping duo go back to the 1970s to visit a haunted house. Jenna-Louise Coleman, who plays companion Clara, tells TVGuide.com, "It's very eerie and haunted, and I think the Doctor (Matt Smith) and Clara arrive kind of wanting to play a bit. But actually in Doctor Who-style, it's more than what we think."

"Hide," which just happens to be the first Doctor Who episode that Coleman ever shot, takes place at Caliburn House, which sits by itself on a desolate moor. A ghost-hunting professor (Dougray Scott) and a psychic (Call the Midwife's Jessica Raine) are investigating an apparition known as the Witch of the Well.

"Dougray Scott's character has equipment to pick up a certain frequency," Coleman explains. "They're talking to the dead and the spirit that's in the house. So we turn up and totally gate-crash. And Dougray Scott and Jessica Raine's characters, they're not together, but you can tell that they like each other."

And unlike Clara's previous adventures on the alien planet of Akhaten or in a Russian submarine, the series' production team did not have to create a set from scratch. "We went to an actual house," Coleman says. "We were bang in the middle of summer here, and it was beautiful. We were sunbathing outside of this huge, country, beautiful mansion and then everything is blacked out into the darkened set."

Despite the subject matter and Doctor Who's reputation for creating frightening monsters, Coleman admits, "I'm not a massive horror fan. Those thrillers when you know something's going to jump out any moment -- it all stresses me out. I watched Alien for the first time recently. That kind of suspense gets me."
